Too/ll whom, it may concern.-

Be it known that we, ZACHARY T. FRENCH and WILLIAM C. MEYER, of Boston,county of Suffolk, and State of Massachusetts, have inventedanclmprovement in Sole Trimming and Channeling Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters and figures on the drawings representinglike parts. i

In the manufacture of boots and shoes it is sometimes desirable to soout or shape the sole that along the outside of the ball portion of eachshoe the sole projects a greater distance beyond the upper than aroundthe toe or along the inside of the ball portion, and prior to thisinvention, so far as we are aware, such soles have always been cut ortrimmed by hand and the channel cut by hand or by the ordinarychanneling-machine, wherein the channel-knife is guided by a gagebearing against the edge of the sole.

This invention has for its object to so improve the construction ofsole-trimmiu g or sole trimming and channeling machines that this workmay be done mechanically, and as a result the boots or shoes which aretrimmed or trimmed and channeled are allalike.

Sole-trimmin g or trimming and channeling machines to which ourinvention is applicable are those wherein the sole is trimmed or trimmedand channeled after it has been socured to and while upon the last, theguide or gage at such time bearing against the upper drawn over the lastor entering the inseam or crease at the welt side of the sole, and incarrying out our invention the relative positions of the guide or gageand the sole trimming and channeling knives are changed during thetrimming and channeling operationas, for instance, said parts occupy acertain relative position when trimming and channeling the sole alongthe inside ball portion and end of the toe, but are caused to occupydifferent relative positions when trimming or channeling along theoutside ball portionand by such change in the relative positions of theparts the edge of the sole may be trimmed off so as to project a greaterdistance beyond the upper along the outside 'bination, with soletrimming and ball portion than along the end of the toe and inside ballportion.

Our present invention therefore consistsin the combination of atrimming-knife, aguide or gage, and means for automatically varyin g therelativepositions of said knife and guide during the trimming operationto Vary the distance from the last that the shoe shall be trimmed,andmeans for throwing said automatic means into action during the trimmingoperation; also, in the combination, with sole trimming and channelingknives, of a guide at the welt side of the sole, a support therefor, andmeans for automatically varying the relative position of said guide andthe trimming and channeling knives during the trimming and channelingoperation; also, in the comchanneling knives, of a guide at the weltside of the sole, means for automatically varying the relative positionof said guide and the trimming and channeling knives during the trimmingand channeling operation, and means for throwing said automatic meansinto action during the trimming and channeling operation.

Herein we have represented our improvements as applied to the soletrimming and channeling machine shown in Letters Patent No.g600,883,granted to us March 22, 1898, to which reference may be had.

Figure 1 shows in side elevation the sole trimming and channelingmachine represented in application for Letters Patent Serial No.530,848, provided with mechanism embody ing this invention for varyingthe relative position of the guide and knives, whereby the outside ballportion of the sole is made to proj ect a greater distancebeyond theupper than the remaining portion of the sole; Figs. 2 and views of theright and left soles; Fig. 4, a detail of a lifting device for the latchor pawl, which engages a notched collar or hub on a sleeve carrying thecam; Fig. 5, a front view of a portion of the machine shown in Fig. 1';Fig. 6, a left-hand side view of, the machine shown in Fig. 1, thebaseand some of the ad? jacent parts being broken away; Fig. 7, a'de-'tail showing the relative positions of the knife and guide at thejunction of the shank and outside ball portion of the left shoe,together with the mechanism for varying their relative positions; Fig.8, a similar detail showing the relative positions of the knife andguide at the forward end of the outside ball portion of a left shoe;Fig. 9, a similar detail showing particularly the reversed position ofthe latch or pawl which engages the notched collar or hub, the cam beingin the position it will occupy when at the forward end of the outsideball portion of a right shoe; Fig. 10, a section al detail showing thecam and notched collar or hub and rotary reciprocating knifecarryingarm; Figs. 11 and 12, details of the notched collar or hub; Figs. 13,14, 15, and 16, details of the latch-con trolling mechanism to bereferred to.

The machine herein shown and to which our invention is appliedcomprises, essentially, a

trimming-knife 3, attached to the lower end of an arm 6, projecting froma hub 6 mounted upon the shaft 01 said arm e being connectedby a link 8with an eccentric-strap which embraces an eccentric disk secured to themain shaft 0, so that as the shaft 0 rotates the knife will beoscillated toward and from the operator acting upon the bottom of thesole. The machine has also a stationary work-support a, made tapering atits lower end to enter the inseam or crease at the Welt side of thesole, and also intermittent feeding mechanism consisting of a yieldingvibrating sole-support b acting against the bottom of the sole, and afour-motion plate d, acting against the welt side of the solo. The plateat also serves as a cutting-block, against which the oscillating knife eoperates, and the sole-support b is constructed and arranged to carrythe channeling-knife b.

The work-support a serves as a rest against the welt side of the solewhile the four-motion feeding-plate d is moving and also as a guide toenter the inseam or crease; but its function as a crease-guide ceaseswhen trimming and channeling around the fore part, another guide f,attached to an arm f, pivoted at f being brought into engagement withthe shoe during the performance of this part of the work, said guide fbearing against the upper drawn over the last, and therefore may betermed the last-guide. The guide-arm'f is connected by a chain orotherwise with a treadle, so that it may be brought into operativeposition whenever desired, and whenever brought into operative positionthe part a serves only as a work-support.

As before stated, in order to carryout this invention we vary therelative positions of the guide and the trimming and channeling knives,and we have herein selected the last-guide f as the guide to be movedduring the act of trimming and channeling the sole, so as to vary itsposition relative to the trimming and channeling knives, because as themachine is herein constructed and arranged this is the guide which isbroughtinto operation at that part of the shoe where it is desired tovary the width of the projecting suitable bearin gs provided for it.

portion of the sole. In other trimming of trimming and channelingmachines wherein but one guide is employed, which acts around both theshank and fore part of the boot or shoe, our improvements, to bedescribed, are made to act upon or work in conjunction with such guide,whether the guide acts in the crease or against the upper drawn over thelast.

The guide-arm f has an upward extension f bearing a cam-roll f and hasalso at its upper end a latch f, movable obliquely in This latch isherein shown as a pin having a beveled lower end and a cross-piece orpin f at its upper end, and inside the bearing a spring encircles thepin, the tendency of which is to depress it. The upper end of theextension 7 is shouldered or cut away, asshown in Figs. 1 and 16, sothat when the pin f is depressed the cross-piece f enters said cutawayportion'; but when raised or withdrawn and given a quarter-turn thecross-piece f will rest upon the upper end of the extension, holding thepin in its elevated position, and when the pin is turned a furtherquarter .of a revolution in either direction the crosspiece f againenters the cut-away portion as the pin descends.

The oscillating knife-carrying hub or sleeve 6 is extended, as at ealong the shaft d (see Fig. 10,) and upon said sleeve-like extension anotched collar or rim 0?. (see Figs. 10, 11, and 12) is placed, which isherein shown as formed with several lateral projections at upon one sideand a sinoothreduced portion n upon the other side of its notched part.Pieces of leather may be inserted between the projections n on thenotched collar n and a clamping-ring m provided which embraces saidprojections, and the interposed pieces of leather acting to frictionallybind the notched collar to the oscillating sleeve 6 Anotherclamping-ring m embraces the smooth portion 12 of the notched collar,which has formed on it a cam m The notched part it of the collar islocated beneath the latch f and the cam on beneath the cam-roll f. Thearmf, carrying the guidef, is normally in its elevated position, asrepresented in Figs. 1 and 6, and when it is brought into operativeposition to be used as the fore-part or last guide the cam-roll f willbear upon the cam m as represented in Figs. 7 to 9. While the latch fremains in its elevated position the notched collar 'n is not engagedand the cam-roll f will rest idly upon-the cam, and the relativeposition of the guidef and trimming and channeling knives will remainthe same; but as soon as the latch is operated its lower beveled endenters the notches cut in the part n, as shown in Fig. 7, and as thesleeve e oscillates the cam is intermittingl y rotated until the stop mis brought up against the cam-roll, as represented in Fig. 8. During thetravel or progress of the cam m the guide f is automatic- IIS allygradually raised relatively to the trimming and channeling knives, sothat the projecting edge of the sole is gradually narrowed. The shoethus introduced and referred to is a left shoe, and the edge of the solealong the outside of the ball portion is thus trimmed off and left widerthan around the toe and inside ball portion.

When trimming and channeling the rightshoe, the work is begun at theright-hand side, as in the left shoe, and while the latch f remains inits elevated position the camroll f rests idly upon the cam m at itshighest part, (see Fig. 9;) but just after passing around the toe thelatch f is turned in the opposite way to that previously described,entering the notched collar with its beveled end turned in the oppositeway, so that as the sleeve 6 continues to oscillate the cam isintermittingly moved in the opposite way, the

cam-roll following along the gradually-re-.

duced portion of the cam, and the guidef automatically graduallylowering relatively to the trimming andchanneling knives along theoutside of the ball portion of the shoe until the stop m is brought upagainst the camroll and the edge of the sole will at such time projectwidest from the upper. At the beginning of the shank portion thisfore-part or last guide is removed from its engagement with the shoe andthe trimming and channeling operation continued, the shoe being guidedby the work-support or crease-guide a. Thus the intermittent motion ofthe cam m is reversed for right and left shoes, so that by employing asingle cam both shoes may be trimmed or trimmed and channeled in thepeculiar style desired, leaving the wider projecting edge of the solealong the outside of the ball portion in each shoe.

As a simple and efficient means of operating the latch f 14 we mayemploy the following mechanism, (see Figs. 1, 4:, 5, 6, and 13 to 16:) Arod 19 is arranged horizontally in bearings 13, secured .to theframework, and to said rod is affixed a finger 19 the upper side or faceof which is beveled in opposite ways, and this finger projects towardthe latch, but located beneath the cross piece or pin f when the latchis in its elevated position, and is arranged to act upon said pinf aswill be described. The rod 13 is movable longitudinally in its bearingsin order that the finger 19 may occupy a position with one or the otherbeveled face directly beneath the pin f on the latch f, and said rod isalso free to be turned or rocked that the finger 11 may be lifted topermit the return of the pin. A detent w is pivoted to a stud 5,projecting from a part 19 on the rod 1), but connected and movablelongitudinally with said rod, said detent engaging a cut-away plate toon the frame when the rod is in its extreme left-hand position, a spring1H2 being connected to said detent to draw it in. A spring to encirclesthe rod p and is connected at one end to the frame and at the other endto the finger 19 or it may be the rod, the action of which is to movethe rod and its attached finger 19 toward the right whenever the detentw disengages the plate 10. An arm 104 is secured to the shaft of theguide-arm f, which has a spring-pressed latch L05 at its upper end,which as the guidearm is depressed strikes and disengages the detent wto thereby allow the rod 19 to move toward the right. The rod p and itsattached parts are afterward moved toward the left or restored to theirnormal position by the operator pressing upon the knob 10 Assuming theparts are in the position shown in Figs. 5, 13, and 15 and the operatordesires to vary the width of the sole, he depresses the arm f by meansof a treadle connected thereto, and in doing so the pin strikes theright beveled face of the finger 172, and moving along said face islifted and also turned substantially a quarter of a revolution, as shownin Fig. 16, and the latch to then strikes the detent w, disengaging itfrom the plate to, and the spring-pressed rod 19 thus released is movedtoward the right, carrying with it. the finger 19 which is fixed to it,and the latter during its passage strikes the pin f and turns it fartherto the right,

so that it will fall .into the cutaway portion, and at such time thelatch f is thrown into engagement with the notched collar. Theguide-actuating cam is then intermittingly turned. It will be seen thatthe latch f is thus automatically turned one way by the act ofdepressing the guide-arm, The guide-arm is then elevated upon releasingthe treadle, returning to the position shown in Fig. 1, the finger prising to allow the passage of the pin fl When operating on the nextshoe of the pair, the guide-arm is again depressed at the desired timeand the pin f turned a quarter of a revolution by striking and movingalong upon the left beveled face of the finger p and then the rod 19 ispushed toward the left by the operator striking upon the knob 2 0 andduring such movement the finger 9 hearing against the pin moves itsuificiently for the latch f to again drop into engagement with thenotched collar and the detent to will at such time be moved intoengagement with the cut-away plate to. Thus it will be seen that thelatch f is reversed each time it is depressed or caused to engage thenotched collar. We do not desire, however, to limit our invention tothis means of operating the latch f It will be observed that a camconstructed and arranged to be reversed, as herein de-v scribed, actsboth to raise and lower the guide with relation to the knife; but weintend to include within the spirit and scope of our invention anyequivalent device or devices by which the guide and knives may be movedone with relation to the other while trimming or trimming and channelinga sole, that the width of the projecting edge of the sole may be varied,and particularly any device or devices acting upon or in conjunc- ICCarm 19 bearing the pin and the arm 19 hearing a. pin and when the rod 19is in proper position for the finger 10 to cooperate with the latch fthe pin 19 bears against the support p; but whenever desired the rod 19may be oscillated, the finger p moved out of cooperative relation withthe latch f and at such time the pin 5 will bear against the support p.

henever it is desired to use the machine without the cam or itsequivalent device, whereby the width of the projecting edge of the solemay be varied along the fore part and yet so trim the sole that it willproject a greater distance beyond the last or inseam around the forepart than along the shank portion, the bevel-faced finger will be movedthe pin on the latch f its full distance toward the right, and then thefirst time the last-guide is depressed will strike the left beveled faceof the finger and be thereby turned a quarter of a revolution, at suchtime resting upon the upper end of the hearing. or

frame, and it will remain in such position until the rod 10 ispositively moved by the operator striking the knob on the end of therod, and hence whenever it is so desired to use the machine the operatorpermits the latch to continuously remain in this position.

The last-guide f is or may be made ad j ustable-as, for instance, it maybe connected to the arm f by aset-screw passing through a slot cut inthe part f, so that said part f may he raised or lowered, as desired, inorder that the width of the projecting edge of the sole around the forepart may be more or less, as desired, although in such case such Widthisthe same all around the fore part,yet greater than along the shankportion, and this adjustability of the last-guide also forms a part ofour present invention.

The machine herein shown contains tri n1- ming and channeling knives andfeeding mechanism for the work and a guiding device for the work movablefreely toward and from the trimming and channeling knives during thetrimming and channeling operation to vary the position of the boot orshoe with relation to said knives, and thereby vary the width of theprojecting edge of the sole;

but/such feature is not herein claimed, as it forms the subject-matterof our application Serial No. 572,258.
